Monitoring the Nagios process with monit

Howto to install monit on Debian or Ubuntu to monitor the nagios process.

Installation

aptitude install monit

Configuration

Edit the monit configuration file /etc/monit/monitrc and make the following changes:

Generall settings:

set daemon  120
set logfile syslog facility log_daemon
set mailserver localhost
set mail-format { from: monit@myserver.de }
set alert admin@myserver.de

Check the nagios process:

check process nagios3 with pidfile /var/run/nagios3/nagios3.pid
        start program = "/etc/init.d/nagios3 start"
        stop  program = "/etc/init.d/nagios3 stop"
        if 3 restarts within 3 cycles then timeout

If nagios is not running, monit tries to start it 3 times. And send you an e-mail.

Note: If you use Centreon the pid file is /var/lib/nagios3/nagios.lock . You have to replace it in the monit configuration file or change the „Lock File“ value in your centreon configuration.

Change the following value in /etc/default/monit to:

startup=1

Start monit

/etc/init.d/monit start
